ObjC function UCKeyTranslate 可以从 JavaScript 用于自动化吗？

Question

In an osascript/JXA context, I need to map macOS keyCodes and modifiers to Unicode strings (for any keyboard layout, specified at run-time)

The obvious candidate appears to be UCKeyTranslate , but my attempts to get a reference to it from a JavaScript for Automation context have not been successful so far.

Does anybody know how to do this, perhaps in terms of ObjC.bindFunction ?

Answer 1

One way to go would be to make a Swift or ObjC helper library (or a command line tool), and then use that from JXA. Check some example code to start .

If you wrap this call in an ObjC object method inside a framework, it's possible to ObjC.import() it and use in your scripts. If you choose to do a command line app, then call it as a shell command.

Using ObjC.bindFunction seems a bit too complicated, because you'd have to bind a few other functions that would get you a UCKeyboardLayout instance, and define a bunch of magic constants, plus do some necessary mapping of strings and pointers.
